| (2) STEP IRONS. These will be the same as the present 25HP., and in approx: the same position. If it is thought that we must do some reduction in the weight of the step irons, wing stays, and body brackets, then we suggest that the same dies be used but the gauge of the material for the pressings be dropped one size.
